The object of the present invention is to provide a coating material for recycling a thermoplastic resin mold, wherein said coating material is coated on the surface of said thermoplastic resin mold and said thermoplastic resin mold, discarded, can be recycled without removing the coating film of said coating material.To attain said object, a thermoplastic resin mold is coated with a coating material containing a thermoplastic resin and non-yellowing type cellulose derivative as vehicles, said thermoplastic resin having compatibility with the thermoplastic resin of said thermoplastic resin mold. Said thermoplastic resin mold, surface coated, used, and discarded, can be recycled without removing the coating film of said coating material, and further the resulting recycled thermoplastic resin mold does not degrade.
